Abstract

The invention relates to the treatment of industrial and storm sewage, where there is an uneven flow regime and the required uniform discharge of clarified water. The purpose of the invention is to improve the cleaning efficiency of the discharged water by improving the hydraulic mode, operation of the device regardless of the change in the level of the liquid. The oil and clarified water drainage unit in the device is made in the form of two horizontal coaxially connected pipes with longitudinal slotted holes located on opposite sides. For vertical movement along the guides, grooves are provided at the ends of the pipes. Internal pipe communicates with the clarified liquid outlet. The device is equipped with a level sensor. 3 il.

The invention relates to the treatment of industrial and storm sewage, in particular to devices for the joint treatment and accumulation of rain and industrial wastewater, where there is an uneven flow regime and the required uniform discharge of clarified water.

The purpose of the invention is to increase the effi ciency of water purification by improving the hydraulic mode of operation of the device, regardless of the change in its fluid level.

- FIG. 1 shows a device for purifying water from oils and mechanical impurities; in fig. 2 shows section A-A in FIG. 1, in FIG. 3 shows a section BB in FIG. one.

The device includes a housing 1 ,. supplying contaminated water to tray 2, sludge at ice 3, clarified water drainage unit in the form of a pipe 4 with slotted holes 5 connected to a telescopic branch pipe 6 and a pipe 7 located inside pipe 4 having slotted holes 8 to collect oils, pipe 7 is connected. with a telescopic pipe 9 for draining oils; the pipe 10 is removed from the oil casing and the clarified water is removed by pipe 11. At the ends of pipes 4 and 7 there are grooves 12 for restricting their movement along guides 13. At the same time, the grooves are fitted with seals preventing ingress of oil into the discharge clarified water. The oil and clarified water drainage unit by the stem 14 is rigidly connected to the electric drive 15. A level sensor 16 is provided for measuring the level of liquid in the device. The precipitate is removed as it is accumulated from the grab with a grab 17.

The device works as follows.

Sewage water containing oils and mechanical impurities, through tray 2, enters the housing 1 for settling. The largest inclusions of suspended solids immediately fall out in wet 3, and the precipitation of a smaller suspension occurs as the liquid passes through the entire length of the device. The accumulated sediment from primka is periodically removed by a grab 17. Oil is collected from the surface by slit holes 8 of pipe 7 and removed by a telescopic tube 9. At the same time slit holes for

The collection of oils is located at the top of the liquid level in the device, and the holes that drain the clarified water are on the opposite side.

Thus, the water, purified from suspended matter and oils, enters the zone of clarified water and through the slit holes 5 of the pipe 4 into the telescopic pipe 6 and pipe 11 discharges from the housing. Due to the uneven flow of wastewater, the level in the device varies. Level change signal

from the sensor 16 level to the actuator 15, which moves the node outlet in the vertical plane. The maintenance of the node for the removal of oils and clarified water afloat is accomplished by a rigid electrically-driven stem design. Between the parts of the telescopic nozzles there are seals that do not prevent the sliding of the links. The use of the oil drainage unit and clarified water in the form of two horizontal insulated coaxial pipes with slotted holes allows the drainage of clarified water to be carried out evenly.

over the entire width of the device, eliminating vortex and stagnant zones, as a result, the degree of purification of the diverted water increases
